How to use Green Screen option?

Sorry this is such a general question, but I have very limited internet access here at work (can't even access Google) and I would like to figure this out before I leave for the day so I can grab what I need on the way home.
We are making weekly comical "newscast" type videos, and we have been using PhotoBooth to make it look like we are in a news room.
I would like to stop using PhotoBooth (due to the obvious extreme limitations in video/audio quality) and use the green screen option in iMovie 09.
Would anybody be so kind as to give a brief couple of paragraphs on the best way to accomplish this?
I have seen the option pop up when inserting a clip on top of another, but which one is the footage/image to replace the green area... the original clip or the overlayed clip?
And is there a specific shade/type of green that works best? Or can I just pick up a dozen yards of general "crayola" green fabric to cover a wall?

I have tried but haven't had much luck. Although I am having a problem with Snow Leopard and iMovie right now. That may be affecting my success. Here are the instructions out of iMovie help.
To use green-screen effects to superimpose video:
Record video in front of a solid green backdrop, and then import it into iMovie.
When you record, for best results do the following:
Use a pure (highly saturated) color of green for the backdrop.
The best color of green to use is often called “chroma key green” in paint and cloth.
Make sure the subject doesn’t have any green clothing, and don’t include anything green in the shot, other than the backdrop.
If possible, use multiple lighting sources to eliminate shadows on the subject being recorded.
Include a moment at the end of the recording with the subject out of the frame. This indicates to iMovie what should be left out when the video is superimposed.
Choose iMovie > Preferences, click General, and then make sure Show Advanced Tools is selected.
In the Event Browser, select video that you recorded in front of the green backdrop.
Drag the selection directly over a clip in your project (video, solid color, or animated background clip), and release the mouse button when the cursor displays a green plus sign .
Choose Green Screen from the list of options that appears.
The green-screen clip appears with a green border around it above the video clip in your project. You can drag it to a different spot to reposition it, or drag the ends to lengthen or shorten it.
To more effectively mask areas of the green-screen clip, select the clip in your project, in the viewer click Cropped, and then drag the handles at the top of the viewer to more tightly enclose the subject of the video.
Anything outside the highlighted area in the green-screen clip is removed from the picture. Be sure not to crop out areas that the subject moves into at any point during the green-screen clip.
To produce a better-quality effect, double-click the green-screen clip in your project to open the inspector, then select “Subtract last frame.” iMovie uses information in the last frame to determine what to subtract from the finished clip.
Selecting “Subtract last frame” works only if you included a moment at the end of the green-screen footage with the subject completely out of the frame.
To watch the clip, click the Play Clip button in the viewer.

I am creating a video using the green screen option- I imported a picture for the background of the project and videotaped someone using a green screen. Is it possible to move the video of the person around so it is not blocking the picture behind it?

To enable this right you need Acrobat, not the free Reader.
However, starting from Reader X it is possible to add simple markups to any file, unless it has been specifically disallowed by the creator of the file.

How do I get blue/green screen option & split screen?

How do I get blue/green screen option & split screen? On iMovie, these options were presented to me, whenever I dragged a clip over another clip already in timeline. Where do I find these choices in Final Cut X ? Also, on iMovie, to resume project production, I would then hit the "done" button -- Where do I find a button to finalize changes? Also , where do I find the option of "precision editor" ? Thanks

Green screen is done with the Keyer effect.
There is no Done except for transformations in the viewer.
Double click an edit point to open the Precision Editor.

How do you use green screen and picture in picture in iMoive at the same scene?

I understand how to do green screen and picture and picture... but how do you do it in the same sequence.. so when you are speaking with a background picture and you want to add a picture or a story within that picture... there has to be a way to do that..

That is a great idea! So I just do everything to the clip involving the green screen. Export it to, say my desktop. Then import it back into iMovie. Then I will be able to add a picture in picture? Fantastic! Thanks so much!

How to use 'several screen function' used to be in os x 10.6

hi ! ^^
how r u ? good !
how to use 'several screen function' used to be in os x 10.6 ??
it was possible to change whole screen with 'command + arrow keys' (option + arrow keys maybe ??)
but, in os x 10.7, it seems it is not possible. and instread of it 'mission controls' that is not uesful ..
no windows drive direct access. no several screen function. crash when control panel ask me administration right.
os x 10.5 or 10.4 was much easy to control.
plz fix and add good functions of 10.6 , remove good functions is not called 'upgrade'.

You can still do it with CONTROL + Arrow keys, the same as 10.6

IMovie: Green screen option disappears?

Hi I recently started using the green screen sollution iMoive provides, and it works alright.
BUT! after putting at bg image and a green screen image together something weird happens, if I decide to put extra bg material after the sequence or erase everything and start over in the same project, the green screen option disappears. together with the insert picture in picture aso. why does it do that.? anyone else has that problem?

Hi
And Advanced tools still ON - or did it go to OFF also ?
I would try - Create a new User-Account and log into this and see if iMovie behaves. This forces Your Mac to create ALL pref. files as New - and if all works OK now then this indicates where to find the problem.

How to use split screen on a mac like on windows 7

how to use split screen on a mac like on windows 7

It does not function the same as windows, in that it does not have an automatic snap function. You can put multiple apps up side by side though. You might want to consider using Spaces instead.

How can I put transitions btw clips that both use green screen?

Seems that when I drop the transition between the clips (between the backgrounds -- it won't let me drop the transition between the videos shot with the green screen), it then pushes the green screened video clips together, and the transition doesn't play at all!

iMovie does all rendering in one pass. This effect would require a nested render, which FCP excels at.
If you want to do this in iMovie, do the first green screen clip. Share it using Export Using QuickTime in Apple Intermediatae Codec. Do the same with the second green screen clip. Then import both clips into an iMovie event. Now you can drag both these clips into a project and put a transition between them.

How to export green screen footage.

I recently shot on a green screen, i keyed it in after effects with keylight but want to do color correction in FINAL CUT. when i export the video it comes out with a black background instead of transparency so it doesn't allow me to composite footage over the background so i can't color correct or do anything because the clips with the black solid background are useless. how can i export the already keyed footage so that i keep the transparency for the background?????
thanks

This thread has become a mess of confusing information. Just to clarify a few points:
1GB RAM is not really enough to run AE well. Your purchase of 4GB is a smart move.
AE manages its own RAM usage, so its very possible that it may only use 20% of available RAM, depending on the contents of your project and the amount of precomping etc that you've used. Once you have the extra RAM, enabling Multi-Processor rendering is the best way to utilize RAM during the rendering process.
The "Secret" option mentioned refers to a secret preference menu in AE, which is enabled by holding the Shift key while choosing preferences. Unless there is clear evidence that your system is running out of RAM while rendering, there's no need for you to use the Secret prefs menu.
The "3 GB switch" referred to is not relevant in your case - it applies strictly to Windows XP users.
In summary, install the extra RAM and activate multi-processor rendering to speed up your renders.
Export your keyed footage using the "Lossless with alpha" Output Module in the Render Queue. This will provide transparency info when you take the footage to FCP.
Alternately, as suggested by Mylenium, do the colour correction within AE.

Using Green Screen tool after project roughcut complete

Hi peeps,
I know how to use the Green Screen tool in iMovie but my problem is I want to apply it to a project which I have already edited. So the usual process is drag your background into project then drag your clip from events on top... but I have already painfully edited my project and want to apply a background to it minus the green screens, can it be done at this stage?
cheers,
BB.

Also, try looking up the term "garbage matte." It's relatively simple concept that can be executed using many different tools and levels of sophistication.
Here's my workflow for standard greenscreen work, stuff that isn't too action-oriented, similar to conventional weather presentations:
1. Capture the footage in Final Cut Pro.
2. Seldct the takes.
3. IMport the best takes into After Effects.
4. Apply masking to the video to remove as much unnecessary stuff as possible using as few vertices in the mask as possible.
5. Apply Keylight.
6. Export to ProRes4444.
7. Import back into FCP.
Additional work might be required for wire or rig removal, rotoscoping for movement in front of or behind foreground objects, masking replacement layers to manage stupid costume errors like a green tie, light wrap, spill removal, reflection cancelation, shadow manipulation.

How disable the full screen option in the standard or wireframe video player ?

I was wondering if (and how) it's possible to just disable the full screen option in the controls that appear below the video player (standard or wireframe).
I want to have a video player with the progression bar, play / pause options, the counter without the full screen option because: "When someone clicks the Full Screen button during playback, the video opens in a pop-up window. Any interaction used to transition to a new state in the application does not work."

Thanks for your help.

I don't think so from within Flash Catalyst. That is all part of the component. I took a quick look at the docs, and did not see that element at as a parameter. There are only two options I can think of: either build a custom controller in Flash Catalyst (which may not have all the same functionality as the stock controller) or take your project into Flash Builder and modify the controller skin there.

How to fix green screen blotches on teeth in imovie 10.0.7

There are green blotches on the individual's teeth from the green screen used. I need to know how to fix in imovie 10.0.7.

"Did you have spinach for dinner?" ... SCNR!
And such a nice smile, 'priceless' and most probably not to be re-done, right?
sorry, to say, but that reaches the limits of lil' iMovie.
You can not manually adjust the color-key in iMovie, as you can do in FCPX, nor does it offer any 'masking' features as Motion would...
.. FCPX offers a 30d free and fully functional (no watermarks etc) trial ... but then you have to learn how to handle color-key in that pro app ... which is not a beginners task ...
